Correct option is (a) 10

The explanation is: We know that voltage across the capacitor in resonance condition is equal to Q times the source voltage.

Q=VC/VS   where VC is capacitive voltage and VS is source voltage.                                                                                                                       Q=1000/100 = 10 V.
